I got 5 to 10 calls per day. then I called customer care and informed them that I am getting too many calls as it is prepaid if I want to continue I will pay otherwise not. and I requested them to avoid the calls and sms regarding renewal. still repeated. on 30.04.2016 n 01.05.2016 I got sms that my account no is deactivated from 01.05.2016. even to day I am getting minimum 2 calls and 2 sms which are harassing me. almost I informed to customer care number[protected] more than 10 times. still problem not resolved. please help me out not to get calls from sadist psycho hatchway broadband.
